Wales manager Chris Coleman felt his side had been on the wrong end of some poor refereeing decisions as they started their World Cup qualifying campaign with a 2-0 defeat against Belgium in Cardiff.
The Dragons had made a solid start to their opening Group A fixture against the heavily-fancied visitors at Cardiff City Stadium before James Collins was shown a straight red card by Swedish official Stefan Johannesson for a reckless lunge on Guillaume Gillet after 25 minutes.
The West Ham defender and several of his team-mates appeared exasperated by the decision, but replays suggested the 29-year-old had few grounds for complaint.
The hosts' hopes crumbled from that moment as Vincent Kompany's 42nd-minute header and Jan Vertonghen's ferocious free-kick seven minutes from time gave Belgium the three points.
But Coleman was highly critical of the sending-off, and Gillet's behaviour following the challenge.
Coleman was also less than impressed with the decision to penalise captain Aaron Ramsey for a foul on Romelu Lukaku, which allowed Tottenham defender Vertonghen to fire home the clincher.
Wales were without several first-choice players with Joe Allen, Craig Bellamy, Neil Taylor, Andrew Crofts and Wayne Hennessey all absent.
Liverpool midfielder Allen was a late withdrawal through illness, but Coleman is hopeful he will be available for Tuesday's meeting with Serbia.
